However, scallops and abalone had extremely low vitamin B12 contents (0.1–1.1 μg/100 g wet weight) which(More)
In this study, we characterized and quantified vitamin B12 compounds in popular edible snails Babylonia japonica and Turdo Batillus cornutus using a microbiological assay based on Lactobacillus delbrueckii subsp. lactis ATCC 7830.
